What are the limits of filial disobedience (ʿuqūq al-wālidayn)? Is anger at their actions or a father's complaint against the mother in court considered disobedience? Does disobedience invalidate good deeds? And how can it be avoided?

The criterion for filial impiety ( uquq al-walidayn) is the occurrence of intentional harm from the child towards one or both parents. Otherwise, mere anger at a parent's action is not considered filial impiety unless it leads to harm, even if slight. If the father is unjust, then it is an act of filial piety (birr) to gently restrain him. Filial impiety is one of the major sins, but it does not nullify the reward of good deeds. To avoid filial impiety, one should recall the great rights of parents and be mindful of the severity of filial impiety.
